WARNING
Do not disconnect modules or wires unless the power supply has
been switched off or the area is known to be non-hazardous. The
devices may only be connected to the supply voltage shown on
the type plate.
The devices are designed for operation with a Safety Extra-Low
Voltage. Thus, they may only be connected to the supply voltage
connections and to the signal contact with the Saf
Voltages (SELV) in compliance with IEC950/ EN
VDE0805.
WARNING
Substitution of components may impair suitability for Class I,
Division 2, and Zone 2. These devices must be supplied by an
SELV source as defined in Low Voltage Directive 73/23/EEC
and 93/68/EEC.

WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Ethernet Switch.
Calculate the maximum possible current in each power wire and
common
wire. Observe all electrical codes dictating
maximu

You should also pay attention to the following items:
Use separate paths to route wiring for power and devices. If power wiring
and device wiring paths must cross, make sure the wires are perpendicular
at
the intersection point.
N
OTE: Do not run signal or
communications wiring and power wiring in
the same wire conduit. To avoid interference, wires with different signal
characteristics should be routed separately.
